▎ 摘　　要

NOVELTY - Insulated composite rope comprises a core layer (1) connected with a cladding layer (3) through a reinforcing member (2), where the cladding layer is made of high molecular weight cross-linked polyethylene material. The outer layer of the cladding layer is provided with an insulating layer (4). The outer layer of the insulating layer is sprayed with a coating layer, where the spraying thickness is 1-4 mm. The preparation method of the coating layer is as follows: adding graphene into butyl acetate solution, stirring for 10-20 minutes at speed of 500-1000 revolutions/minute, adding aminosiloxane, continuously stirring for 10-20 minutes, adding modified wollastonite powder, and continuously stirring for 35-45 minutes to obtain a coating layer. USE - Used as insulating composite rope cable. ADVANTAGE - The insulating composite rope cable has more stable structure, improves electrical insulation of the product, removes electric ion, and improves insulating performance of product. DETAILED DESCRIPTION - Insulated composite rope comprises a core layer (1) connected with a cladding layer (3) through a reinforcing member (2), where the cladding layer is made of high molecular weight cross-linked polyethylene material. The outer layer of the cladding layer is provided with an insulating layer (4). The outer layer of the insulating layer is sprayed with a coating layer, where the spraying thickness is 1-4 mm. The preparation method of the insulating layer is as follows: adding 100-140 pts. wt. methylphenyl silicone resin organic resin into the reaction kettle, heating to 210-270℃, reacting for 20-30 minutes, adding 10-40 pts. wt. silane coupling agent KH560 (3-glycidoxypropyl)trimethoxysilane), 5-10 pts. wt. epoxy soybean oil, 3-7 pts. wt. divinylbenzene, continuously stirring for 10-20 minutes at speed of 150-200 revolutions/minute, adding 10-20 pts. wt. modified bentonite, cooling to 120-150℃, continuously reacting for 30-40 minutes, completing the reaction, washing with water, and drying to obtain an insulating layer. The preparation method of the coating layer is as follows: adding graphene into butyl acetate solution, stirring for 10-20 minutes at speed of 500-1000 revolutions/minute, adding aminosiloxane, continuously stirring for 10-20 minutes, adding modified wollastonite powder, and continuously stirring for 35-45 minutes to obtain a coating layer.
